Functional breast cancer literacy was assessed among African-American women and measured at the domain level over time. We
used the Kin KeeperSM Cancer Prevention Intervention to educate 161 African-American women on three domains of breast cancer literacy: (i) cancer
awareness, (ii) knowledge of breast cancer screening modalities and (iii) cancer prevention and control. A breast cancer literacy
assessment was administered pre- and post-educational intervention at two time points followed by another assessment 12 months
after the second intervention. Generalized estimating equations were specified to predict the probability of correctly answering
questions in each domain over time. Domain-level literacy differentials exist; at baseline, women had higher test scores in
the breast cancer prevention and control domain than the cancer awareness domain (odds ratio = 1.67, 95% confidence interval
1.19–2.34). After Kin KeeperSM Cancer Prevention Intervention, African-American women consistently improved their breast cancer literacy in all domains
over the five time stages (P < 0.001) though at different rates for each domain. Differences in domain-level breast cancer literacy highlight the importance
of assessing literacy at the domain level. Interventions to improve African-American women's breast cancer literacy should
focus on knowledge of breast cancer screening modalities and cancer awareness domains.

    ABSTRACT: We examined differences in knowledge and socioeconomic factors associated with 3 types of breast cancer screening (breast self-examination, clinical breast examination, and mammogram) among African American, Arab, and Latina women. Community health workers used a community-based intervention to recruit 341 women (112 Arab, 113 Latina, and 116 African American) in southeastern Michigan to participate in a breast cancer prevention intervention from August through October 2006. Before and after the intervention, women responded to a previously validated 5-item multiple-choice test on breast cancer screening (possible score range: 0 to 5) in their language of preference (English, Spanish, or Arabic). We used generalized estimating equations to analyze data and to account for family-level and individual correlations. Although African American women knew more about breast cancer screening at the baseline (pretest median scores were 4 for African American, 3 for Arab and 3 for Latina women), all groups significantly increased their knowledge after participating in the breast cancer prevention intervention (posttest median scores were 5 for African American and 4 for Arab and Latina women). Generalized estimating equations models show that Arab and Latina women made the most significant gains in posttest scores (P < .001). Racial/ethnic differences in knowledge of breast cancer screening highlight the need for tailored information on breast cancer screening for African American, Arab, and Latina women to promote adherence to breast cancer screening guidelines.

    ABSTRACT: Use of pharmacotherapy for smoking cessation improves quit rates, but these treatments are underutilized, particularly among Black smokers. Attitudes toward pharmacotherapy may differ between racial/ethnic minorities and Caucasian smokers. It was hypothesized that Black and non-Hispanic White smokers would differ in their attitudes toward pharmacotherapy and that the association between attitudes toward and actual use of pharmacotherapy would differ by race. The study consisted of a single, cross-sectional telephone-based survey of current smokers (N = 697), which examined the relationship between race, attitudes toward pharmacotherapy, and pharmacotherapy usage in a representative bi-racial sample (39% Black). Black smokers were significantly less likely to report ever use of pharmacotherapy (23%) than Caucasians (39%; odds ratio [OR] = 0.46; 95% CI: 0.33-0.66). Compared with Caucasians, Blacks had significantly less favorable attitudes toward pharmacotherapy, including disbelief about efficacy (p = .03), addiction concerns (p = .03), harmfulness of pharmacotherapy (p = .008), and need for treatment of any kind to quit smoking (p = .004). In a multiple logistic regression, racial group (Caucasian is referent: OR = 0.55, p = .003), addiction concerns (OR = 0.80, p < .01), and need for treatment of any kind to quit smoking (OR = 1.52, p < .001) were predictive of pharmacotherapy use. Conclusions: These findings replicate and build upon previous research demonstrating underutilization of pharmacotherapy and enduring misconceptions about pharmacotherapy, particularly among Black smokers. Regardless of racial group, misconceptions about pharmacotherapy are related to lower rates of use. Efforts to improve understanding about the efficacy and safety of these products are needed to boost utilization and impact cessation rates.

    ABSTRACT: Background: Although breast and cervical cancer deaths have declined due to early screening, detection, and more effective treatment, racial and ethnic disparities persist. This paper describes the study design and baseline characteristics of a randomized controlled trial (RCT) evaluating the effectiveness of the Kin Keeper(SM) Cancer Prevention Intervention, a family-focused educational intervention for underserved women applied in a community-based setting to promote health literacy and screening adherence to address cancer disparities. Methods: Female public health community health workers (CHWs) were trained to administer the intervention. They recruited female clients from their public health program caseload and asked each to assemble two to four adult female family members for the breast and cervical cancer home-based education sessions the CHWs would deliver in English, Spanish or Arabic. We randomized the clients into the kin keeper group (treatment) or the participant client group (control). Results: Complete data were obtained on 514 Black, Latina, and Arab women. Close to half were unemployed and had yearly family income below $20,000. Thirty-four percent had no medical insurance, and 21% had diabetes. Almost 40% had no mammography in the last year. Treatment and control groups were similar on most sociodemographics but showed differences in breast and cervical screening history. Conclusions: This innovative study demonstrates the implementation of an RCT using community-based participatory research, while delivering cancer prevention education across woman's life span with women not connected to the health care system.
